Hi All,
This sound a little dumb but ... Why do you need a 6 chan TX when you on have 5 servos to control? Is it for the gyro? What is the AUX on the RX pack used for and do you use it from the TX?

Thanks

The 6th channel is for the esc i think. ive never actually had a 6 channel setup since i only got into RC heli's bout 3 month ago and am still flying a walkera #4, so dont take my word for it lol

Channel 1 = Ail
Channel 2 = ele
Channel 3 = throttle
Channel 4 = rudder
Channel 5 = gyro
Channel 6 = pitch

Thanks, But what about the AUX port on the RX? I wanted to know what it can be used for like lights or something else. I can't find anything in the JR652 TM about that. Since I bought the Raptor used I'm sure about what model RX I have.

Once again thanks.

Generally speaking, all channels above channel 4 are considered an AUXillary channel. So what AUX are you talking about? 5, 6, 7, 8, ... etc. Channel 5 in HELI mode is typically the gyro sense/mode control. It is only used IF the gyro has that capability (some don't). Since channel 6 has been designated as Pitch control in HELI mode, it's pretty much an AUX channel that is spoken for.
Channel 7 is can be used for controling a throttle control device if you have one onboard.

So in HELI mode, you may have channels 5, 7, & 8 available for anything you want to control. Channel 6 may be available if you are flying a fixed pitch heli where the vertical thrust is controlled by RPM (throttle via ESC) as opposed to collective pitch.

Typically, you need a TX that has the capability to control the channel (ie at least a 7ch TX to control up to ch 7 at the RX).

In order to use your "aux" channel, you need to determine which channel it is. After that, determine if your TX has the capability of controlling that channel (via switch, dial, stick, etc). If that channel is currently NOT in use (ie Aileron, Elevator, Throttle, T/R rotor, Gyro, Pitch, etc), then you can use it for anything you want (within the capability of your system) ... the sky's the limit.

Good Luck,

On the RX it has a port label gear and then rest of the norm ports. So now I've corrected myself what can the gear port be used for? My gyro is pluged into another port. I should be able to use gear on the tx to control something correct? If so do I need to add a switch to the tx to control it. The only way I see to control the gear is with reproraming the tx mid-flight. I might be wrong. Can I add more channels to the TX?

Some tx's also allow you to use channel 7 for gyro control instead of 5. Not sure how that's relevant here but I thought i'd add that. [:-]

Landing Gear ... In airplane mode, the GEAR function in the TX is usually assigned to channel 5. In a TX that has HELI mixes (especially a dedicated GYRO setup screen), the GYRO mixes is usually assigned to channel 5. If the TX has no such GYRO programming, then any (non-programmed) channel can be the gyro channel (as long as you know how to set up the %'s in the TX).
As was said before, your TX has to be able to control the channel you are wanting to use. I've heard of hacking 4 channel TX's to activate the 5th and 6th channels, but as you said, that requires doing stuff to the guts of the TX.

You can use 2, 3, 4 channel TX's on 7,8,9 channel RX's. It's just that you have no control over anything plugged into those channels.

You never mention what model TX you have ...

Good Luck

I have a JR652 have you heard of any mods with those?

thank you for all you input

That's a 6 channel radio. Can't do much to it. What model RX do you have? How many channels on the RX? What channel is the AUX channel?

Good Luck,

Most people buy the higher channel radios for features such as programable mixing, preset mixes, trim step, a gyro and governor menu, more pitch and throttle curve points, etc and not only for the "extra channels"

Typically a gyro gain or heading hold/non heading hold mode switch is assigned to channel 5 and channel 7 finds itself used for a governor, retracts, lighting, a camera trigger or some other "nice to have" trinket.

It also may be interesting to note that a Futaba 9C is only 9 channels in PCM mode and 8 channels in PPM (or what people call FM) mode and even then its only on/off
